True, I didn't learn a whole lot from SS, but it was the most convenient way for me to get the license. There were several in my class that failed the first time and a couple of guys actually flunked out altogether..Don’t know who does online course. I also used sea school for the OUPV, 100 GT and finally 200GT. The goal of the school is to make you pass. Plenty of hints as to which question will be in the test.
In fact for the 200 we did a practice test on the last day... next day the actual exam was the very same test. What a joke.
